Is it possible that the start circuit is incorrectly connected to 240v? If the motor is reversible by moving leads of the start circuit between terminals it is possible to misconnect them.
I want to see this non-Shopsmith motor. They require a special armature length to function. Is this a hybrid motor with a Shopsmith armature?
How did they doi this? The end bells and thrust in and out could be an issue, as field strength of the motor/ armature combo. Could it be a European 50hz motor?
There is a spacer on the shaft for clearance for fan sheave. Is there a possibility the spacer is missing or worn?
The dented sheave is a concern as Russ states.
Lots more questions than answers I’m afraid.
